Another MP has resigned over the Brexit deal in the latest blow to the government since Theresa May unveiled her plan.

Will Quince, Tory MP for Colchester, has quit as ministerial aide to Defence Secretary Gavin Williamson, a Government source revealed tonight.

The politician told The Sunday Telegraph: "I wanted to support this Withdrawal Agreement, and I still want to support it, but unless the backstop is addressed to include either an end date or a unilateral exit mechanism, I cannot support it and so am resigning from the Government as a Parliamentary Private Secretary.

"I implore the Prime Minister to go back to the European Union and find another way, to make this Withdrawal Agreement something we can all support."
